Last we saw of C3 Technologies' 3D mapping software it was making an appearance on Sony Ericsson's X10, but if 9to5Mac turns out to be right, its next stop could be the iPhone. According to the publication, Cupertino recently scooped up the Saab spin-off and C3 execs have since been working closely with the iOS division. Earlier this year, Apple posted job listings, looking for developers to "radically improve how people interact with maps and location-based services." On a related note, the outfit previously acquired Poly9, a web-based mapping company. So is the fruity one looking to up its street (navigation) cred? Is it finally ready to give Google Maps the boot? We'll just have to wait and see.
